To all 117mm il" may cole/cent.'

Be it known that l, WILLIAM H. DAVEN- lon'r, a citizen of the United States, residing at Norwich, in the county of ,New London and. State of Connecticut, have invented certain nei'and useful Improvements in Breakdown Guns, of which the foilowing is a full, clear, and exact description.

This invention firearms and relates particularly te the extractor mechanism thereof.

The object of said invention is to provide simple mechanism applicable particularly to breakdown Shotguns and operated and controiled by the top-snap lever of the arm, the manipulation of said lever serving not only to release the barrel to permit the breaking down of the latter, but also to start the sheii from its seat suiicie'ntly to permit it to be grasped and withdrawn from the barrel. o assist in explaining my invention, l have provided the accompanying sheet of drawings, which serve to illustrate the same, as foilows:

Figure l shows, partly in elevation and partly in section, an arxn fitted up with my newly-invented improvements. Fig. 2 is aview similar to Fig. l, illustrating the arin broken down and serving also to explain the manner in which my said improvements 0perate. Fig. 3 is a cross-sectional view taken ou line l i. 4 is an end viewof the bar rel and its lug. Fig. 5 is a plan view of my newly-invented mechanism.

The principal feature of my newly-in vented ejector mechanism consists in providing an extension to the usual himmel-locking bolt, which extension nearits forward end is adapted to engage a hinged lever hung; in the frame of the arm, the free end of which lever is adjacent to and adapted to engage the forward end of the extractor-red. When the 'top-snap lever is moved to disengage the bei* from the barrel-lng, said bolt engaging the hinged lever above mentioned serves at the saine, time to rock the said lever upward, os hereinafter explained. The init-iai movement of the bolt disengages it from the barreilug, when the barrel may be broken down, after which continued rearward movement of the Doit rocks the free enti of the hinged lever up 'vrindq as seen in Fig. 2, said end engaging the forward of the ejecte -red and forced rearward, as hereinafter forcing the latter rearward. .The head of the e, the hammer; f, the trigger, and g the tcpsnap lever, the above-named several parte being constructed, assembled, and operated in the usual manner, and, being well understood-by these conversantwitb this class o arms, no detailed description or illustration of them or'of the lockworic otwthe arm is deemed 1, necessary.

'lhe barrel-lug c has a chamber 7i located. therein beneath and parallel with the bore of the barrel. ,'lheehamber h is provided for the reception of an extractor-rod s,.bearing on its outer end e.- head lo', which latter when said rod is in its inner or closed position forms a portion of the barrel band partly encircles the ange of the shell, which latter is denoted by the letter m and its lian'ge orhead by thel-etter m'. Whe'n the ertractbnrod is explained, the flange k engages the ange 'm' of the ehelil and moves the shell correspondingly outward to permit it to be readily withdrawn from the barrel. Q

To limit the movement of the rod. 7c and also to prevent its rotation, a Hatte-ned rec-ese 7a2 is provided thereon, weich is engaged by? the inner end of a screw n, located in the lng c, asis beet seen in Fig. 3, the engagemenh of said screw with tho flattened recess k2 prc-i venting,r rotar-ion of the rod /c and its engagement with the end walls of said recess serving to limit the endwise movement of said rod.

The barrel-locking bolt is denoted as e whole by the lettere and, as before nnentione@` has a forwardly-extending portion7 coneerni ing which e. more derailed description is given hereinafter. is foi. i

Said bolt as here shown plate ferm and is adapted to 'travel reciprocaliy within the frame ay in `:grooves a', pro vided in the frame to receive the opposite edges of the holt. in orderhat the long.; hielt o may not interfere 'with the closing of the arm, the lower portion of the lug c is largely cutaway between its opposite ends, thus lea V- ing,r the hook portions C' c2 at saidopposite ends to engage, respectively, the hinge-pin (Z and the bolt 0. The bolt o is provided with an opening o', throughwhich the lug; portion c2 passes when the arm is closed. The porv tion of the bolt o adapted to engage the lug:-

notch c3 is denoted by the reference-letter o2, and Said portion is adapted to be carried into or out ofengugement with said notch as the bolt travels forward and rearward, and to aetuete seid bolt to cause it to travel as just mentioned the top-snap lever g is utilized through thefollowing-described mechanism; The,saidziop-snap-iever is mounted in the usuelmanner upon 'zt-pin g', having?, bearing in the well ci' the framealand having secureda to its;end Within the girame an erm g2, the free end otl which is connected by a link p withtheuboito The bolt o has also secured theretof'azrcd q,.bearing a coiled spring q', that i'con'ii ned between the bolt o (or an angillarbendin the rod q, shown) and a bear ing a'provfided within the frame o, to receive the free -endfof the said rod q. It will` now he seen byreference to Fig. 5 that should the said.- topfsnap level' be 'swung from the pesition'shown `in full lines to that shown 'in doticdliines'the erm g2, movin g in unison there with,Wilhthrough the link p, d raw rearward hebolt oandffthe rod q, and thus compress -theaipring q between the points of its confinement; Upn the release of the topsnep leverl-gthezspring g aton'ce expands and returns th'elseveral elements to Lhei r normal or starting positions.

The hinged lever above mentionedis denoted by theletter s and is shaped substantiallyk as shown in the drawings. Said lever lies ina: 4piane parallel with the length of the fremeend is secured Ybetween the confrontingfa'ces of `the side walls oti the frame beneath the bolt-fo by a pint passingthrough' its rear endend-seated inthe frame, as shown in Fig.- 3,' fll-heftorwardend of the lever s is curved .to passthrongh e slot oin the bolto, and the extreme forward end of said lever pessesf'alsothnogh a slot 71', leading' from the ,charnber hate, the bottom of the lug c, thus allowingfthefree end cf said lever to enter the chamberwh, asjshown. The wall at the forward end-of\ftho slot o is prct'oral'iiy beveled, as etof, and' is thus adapted to engege the .adjacent curved edge of the lever s. it will new be seen that when the arm is. closed,as shoWIiin-,Fig l, should thebolt o be drawn rearwardas above described, the beveled wall o?. o"y the slot o3 will engage the curved front, edge-of.l the lever s and cause said curved edge totravol upward on said beveled wall, and thus rock the free end ofthe lever upward. At about the time or just before the seid free end of the' lever s engages the upper side of the chamber h the bolt portion o2 becomes disengaged from the notch c3, thus permitting the breaking down 0E the barrel. Such operation carries the rear ond of the barrel upward, after which continued movement of the top snap and bolt rocks the lover s and causes its free end* to travel rearward in the chamber h,seid" end. engaging and forcing before it the boltl la, Whose head portion la effects the startingr of the shell, as alreadydescribed. Upon the release of the top-snap lever g the bolt o at once reassumes its forward position and the lever s travels downward in the-slot Igiiret-urning to the position shown in Figi l .1

Upor the reloadingy b'f the arm the bolt lo may be'pushed inward to'Joring the outer face 'of the letter and the ,endi ot" thenew shell flush with the end of the barrel, or such re -sult may be attained upon the closingvof the arm, when said shell andl the extractor are forced inward .by their engagement with the front face ot' the recoil-block a3.

The above-described mechanism operates positively to accomplish -the starting of the shell, and, while two operations are accomplished bythe sliding-of the bolt o, it should be borne in mind that unless purposely operated with an intermittent movement the said operations result from a 'single move ment of the top-snap lever, the starting of the shell occurring substantially simultaneously with the breaking down of the arm.

The abdve-described mechanism is very simple in its construction, is not expensive to produce, and greatly improves the class of firearms to which it relates. f

` Having thus described my invention, I clainil. In a' breakdown arm, in combination,-aJ frame, a barrel, hinged-thereto, having a sliding,r extrectorlas set forth, a bolt mounted to slide in the frame, and apivot'ed lever lying in the path ot' said bolt and adapted to eugage the extractor substrantiallyas specified.

2. lu a breakdown arm, in combination', a frame, a barrel, hinged thereto, haviugzwslid` ing,Y extractor in its lower portion, a slotted bolt mounted to ,slide inthe frame, and a lever located in the bolt-slotg one end of said lever being pivoted in the frame and the other end' extending; upwardA in engagement with the extractor, substantial-ly as specified.
